# AddressZero

Very bad things would happen if you could set `msg.sender` to `address(0)`

during actual execution. The Optimism bridge would be susceptible to attack.

The exploit is very simple, see `src/AddressZero.sol`.

Run the exploit like so:

```bash

$ forge script \

    -vvvvv src/AddressZero.sol \

    --tc AddressZero \

    --rpc-url 

```
